WIND-WHEEL ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 427,483, dated May 6, 1890.. Application filed May 6, 1889. $erial No. 309,777. (No model.) 7

T0 at whom it may concern.-

Be it known that I, RILEY HALsEY SARGENT, a citizen of the United States of America, residing at Walworth, in the county of Custer and State of Nebraska, have invented certain new and useful Improvements in WVind-IVheel Attachments, of which the following is a specification,reference being had therein to the accompanying drawings.

This invention pertains to certain new an d useful improvements in wind-wheel attachments, having reference more especially to a grinding-mill operated by the power derived from the former.

The object of the invention is to provide means for automatically stopping the working of the wind-wheel when nearly all the grain in the hopper has been ground; and it consists of a weighted wing orplate connected with a trigger or trip holding the disengaging and connecting rod of a windmill, the raising of said wing or platecausing said rod to throw the wind-wheel out of gear, substantially as hereinafter fully set forth.

In the accompanying drawings, Figure 1 is a front elevation showing my invention connected to a wind-wheel tower. Fig. 2 is a detail view of the hopper and its valve. Fig. 3 is a view of a modification.

Referring to the drawings, A designates the hopper, leading to a grinding-mill andhaving a lower opening a.

B is a wing or plate provided with a short arm I), projecting through a slot or openingb in the hopper, wherein it is pivoted by a pin b To the'outer end of this arm Z7 is secured a weight 0, to which is connected one end of a rope or chain D, which is connected at its end to a right-angular trip'lever d, fulcru med on a bracket (1 of a wind-wheel tower E.

F is a quadrant or lever fulcrumed to the tower E. To one end thereof is connected the lower end of a rod f, leading to the wind-wheel mechanism, and with its other end the triplever 61' is designed to engage.

A rope or chain G is connected to the upper end of the quadrant or lever F,and after being passed over a pulley g said rope has connected thereto a weight g.

In practice the grain in the hopper holds the wing or plate B down against the side thereof, and the trip-lever d and quadrant orlever F are brought into engagement, which will throw the wind-wheel into gear through the rod f. The power derived from the windwheel will effect the grinding of the grain by means not shown, whereby when the supply of grain in the hopper is nearly exhausted, as shown in Fig. 2, the wing or plate B flies into a horizontal position, causing the lowering of the weight, which will pull on rope or chain D and effect the tripping of the lever 61' and quad rant or lever F. The movement of this quadrant or lever under the action of the weighted rope will pull down on rod and throw the windwheel out of gear, thereby immediately discontinuing the grinding operation.

In Fig. 3 I have shown a modification of my invention, which consists in employing a bellcrank lever H and connecting the same to a lever h by means of a link 71 A trip-hook h is designed to engage said lever h, said hook serving the same purpose as the trip-lever cl. One end of lever h is pivoted at h3 to a bracket or frame 77. and to the other end of said lever is connected a weighted rope, as in Fig. 1.

I claim as my invention- 1. The combination, with a wind\vheel, of the hopper having the automatically-moving wing or plate, the tripping mechanism c011- nected thereto, and the rod leading to the wind-wheel, substantially as set forth.

2. The combination, with a wind-wheel, of the hopper having the pivoted wing or plate, the weight connected thereto, the wind-wheelregulating rod, the lever to which said rod is connected, the trip, and the rope or chain conmeeting said weight and trip, substantially as set forth.

3. The combination, with a wind-wheel, of the hopper having the pivoted wing or plate, theweight connected thereto, the rope or chain, the trip-lever, the quadrant or lever, the weighted rope or chain connected thereto, and the connecting rod or barleading to the windwheel, all constructed and arranged substantially as set forth. v

In testimony whereof I affix my signature in presence of two witnesses.
